Ive been making my own resource pack, and eventually it just disappeared from the local section so i couldnt download my latest version of it, but then i realized it said "http" instead of how it usually said "https" and it even says to switch between the two if you cant find it, but i cant switch no matter what i do, there is no button to switch. Please, i dont want to have to do all the work again that i had done just because i cant switch.

I know this is a few months later, but does your browser support showing http:// vs. https:// in its address bar when you click the address? If so, you may be able to edit it -click the address bar, select http://, and enter an s before the double slashes. If this doesn't work, I have no idea what will.
